Thank you all for your help. I took line loose at the calipers and no fluid comes out. The calipers are not froze and easily move in when pressed on. I will order new flex lines and post back when I get them on. Thanks again.
I am new here so bare with me. I recently inherited my grandfathers 74 c10. I am trying to diagnose the brake system. The truck has manual brakes with disk in front and drum in rear. The truck has a hard brake pedal. I have bleed the rear brakes, but their is no fluid going to the front...
